In a copending application zby Leipert, Serial No. 704,303, filled Apr l.

1924, there is disclosed a construction and w 1 suspension of :seats for vehicles designed with particular reference to seats for :motor vehicles ihavingqas its object the cushioning 'ofrroad shocks, for;instance,;by the pro: vision of non-metallic yielding suspension means-.for the seat frame :and the elimination of use of metallic or similar spring elements. The present invention has for its object to provide a suspension fora vehicle seat which will afford a greater latitudeoif movement of the vehicle seat'whilea-t the same time permitting a -=constr=uction- .in

' which :the anus and aback are unitary there sembly in the interest. of rsimplicityhand cheapness-of results. In order illhfllt-the invention may be clearly understood and read ily carnied into effect the same will now be described more fully with :reference to the accompanying drawings illustrating a preferred embodiment thereof inwhidh:

Figure l :aiview in side elevation showing the vehicle seat according to the present invention. p c h Figure 2 is a view in front elevation of the vehicle seat.

1 Figure 3 is a fragmentary sidegview, part-- ly in section, showing the manner in which the yielding non-metallic cord is associated with the vehicle seat and base therefor to serve as a yielding non-metallic connection and support therebetween.

Figure 1 is a view similar to Figure 3 but showing fragmentary portions of the seat and base when looking from the front.

The invention is not concerned primarily with the specific form taken by the seat as such forms no part of the present invention. The drawings are intended toillustrate merely a conventional type of single seat adapted for use in motor busses ofthe more luxurious type and in which' central pedestals or bases a are adapted to rest upon the floor of the vehicle and support a seat b having a back b'fand arms bt The prin-.

possibleand therefore no resultant disar rangement of clothing will ensue.

a The invention is not to :bedimited to the particular-manner in which the suspension means are -,:a-va.-iled of} the illustration and the following description being given more:- ly as indicative of one way-of using yield ingv non-metallic iCOIdS for the support of the seat. 'lrhe frame of the seat is preferr ably formed as :a pressed metal rectangular portion 0 upon the turned over upper edges 0. of which :the seat cushion :b rests and which is adapted, to sun-round the upper portion of; pedestal a. The bottom :sideedges of frame a turn inwardly at :an angle as at a and onHthe inner sll'llfiwfl thereof are formed :a plurality of blocks -10 @formed' with curved lower isurfacaas grooved preferably to receivethe nonsmetallie connecting 00rd.

To the upper portion of the pedestal a there is secured a frame d having a top plate 01 turned downwardly at the two sides as at d? and formed with apluralit of blocks 03 similar in every respect to the b ocks 0 butv formed with a curved grooved surface uppermost; Y I i To the respective front and rear corners 0*, 0 frame 0 there is secured, atits respec-, tive ends, a length of yieldingnon-metallic cord d", such as aeroplane cord. Such cord consists of strands of rubber and silk. This cord is led downwardly and inwardly to thence-upwardly around the most'forwardly disposed block (13. The cord is thus wound between alternate blocks d and 0, respectively, to the most rearwardly of the blocks from whence it is led upwardly and inwardly to the rear corner d of frame (1 where it is clamped by. a clamp e and then led outwardly and upwardly to the corner a. r 1 a From the foregoing description the advantages and manner of using theimproved suspension should be apparent. The-seat frame cZ carrying the seat 6 and arms and, back b? and b, respectively, is supported yieldinglyby' the lengths of cord. the loops of cord lie in inclined planes along the sides of the seat, not only is adequate support given thereto but a degree of universal movement with suitable constraint is afforded for the seat which contributes to the comfort of the'passenger. The inclined ends of the cords d at the front and rear of the chair resist yieldingly the application of greatest weight whlch will naturally be impressed in a for'e'and aft direction by'an aoccupant'recliningagainst the back or sitting'down or rising from the seat. The lengths (Z also tend to snub any tendency toward vertical movement, It may be possible to assemble the parts with the cord under tension, that is, subject to an internal static load. Subsequent adjustment of its length or tension may be readily made throughthe various clamps e and f. Lateral movements of the seat frame are resisted directly by the inclination of the loops a frame, a seat having a frame outwardly of the 'first named frame, a plurality of blocks having curved surfaces dis osed on the sides of the two frames respectively, alternate surfaces being reversely curved with respect to one another, aflexible cord, means securing the same at itsends to the corners of theseat frame, the cord extending to proximate corners of the base frame, and means to clamp the cord thereon, said cord extending betweenthe blocks having alternate curved surfaces to form a yielding supporttherebetween 2. In combination, a seat frame, a base frame, lengths of flexible cord on each side of the frames and connecting the two, and means to connect the lengths of each side to the frames at a plurality of points, said means being positioned to cause portions of each length to lie in different inclined planes with espectto other portions of the same length. i

In combination, a seat frame a base frame withinthe same and of smaller size, lengths of cord connecting the two, means for connecting the lengths at each end to one frame, and at points intermediate the ends to the frame in a different plane from" that of the first connections, and means for connecting the lengths to the other frame at a point between the ends and in a vertical plane difierentfrom that in which the first connecting means lie, whereby the resultant of the forces-in the portions of each length lies at an'angle to the vertical.
